Flexible coupling Dura-Flex®

for heavy loadssleeve and shear pin

TB Wood’s Dura-Flex® couplings are designed from the ground up using finite element analysis to maximize flex life. Perfect for a wide variety of applications -- including those with uniform to heavy shock loads -- Dura-Flex® couplings employ a light weight element that absorbs shock loading and torsional vibration. These couplings are available in stock bore-to-size (BTS), Taper-Lock® and Sure-Grip® bushed (QD) hubs. Product Features Easy to assemble/replace High misalignment ratings No maintenance/lubrication Part-for-part interchangeable with industry standard design In-stock versatile spacer design can accommodate many configurations with few parts Designed from the ground up using finite element analysis to maximize flex life. Easy two piece element installation. No need to move the hubs during replacement. One spacer size to handle most different between shaft spacings. Light weight element absorbs shock loading and torsional vibration. Same hubs used on both spacer and standard elements. Good chemical resistance.
